Many Buffalo routers ship with DD-WRT, a fork of OpenWRT:

It wasn't a fork of OpenWRT per se. Rather, OpenWRT and DD-WRT are siblings, both having descended from the stock firmware on the Linksys WRT54G. They share some code nowadays, but that's a convergence rather than a divergence.

I wasn't aware, thanks for the clarification!
